Power protection circuit
First Claim
1. A power protection circuit, comprising:
- a power providing unit configured for providing power supply;
a first voltage converter;
a first switch interconnected between the power providing unit and the first voltage converter;
a second voltage converter;
a second switch interconnected between the power providing unit and the second voltage converter;
a first voltage detecting circuit connected to the first voltage converter and the first switch;
a second voltage detecting circuit connected to the second voltage converter and the second switch;
a first warning circuit connected to the first voltage detecting circuit; and
a second warning circuit connected to the second voltage detecting circuit;
wherein when the input voltage of the first voltage detecting circuit drops, the first switch turns off the first voltage converter, and the first warning circuit signals a warning;
when the input voltage of the second voltage detecting circuit drops, the second switch turns off the second voltage converter, and the second warning circuit signals a warning.

Abstract
A power protection circuit includes a power providing unit, a first and second voltage converters, a first and second switches, a first and second voltage detecting circuits, and a first and second warning circuits. The first switch connects between the power providing unit and the first voltage converter. The second switch connects between the power providing unit and the second voltage converter. The first and second voltage detecting circuits are respectively connected to the first and second voltage converters. The first and second warning circuits are respectively connected to the first and second voltage detecting circuits. When the input voltage of the first voltage detecting circuit drops, the first switch turns off the first voltage converter, the first warning circuit signals a warning; when the input voltage of the second voltage detecting circuit drops, the second switch turns off the second voltage converter, the second warning circuit signals a warning.
